After watching the YouTube "EEVblog 1524 - The 10 CENT RISC V Processor! CH32V003",
https://www.youtube.com/watch?v=L9Wrv7nW-S8&ab_channel=EEVblog
I had to learn more about this chip.

Where to get a CH32V003 development board

I ordered this board: along with the programmer and cable for $7.50:
https://www.aliexpress.us/item/3256805035436953.html

Repository for board with documentation and example code: https://github.com/wuxx/nanoCH32V003
The github repo's README.md file: https://github.com/wuxx/nanoCH32V003#readme
                  Schematic: https://github.com/wuxx/nanoCH32V003/blob/master/hardware/nanoCH32V003.pdf

I created a RISC-V folder under Documents like so:
C:\Users\Jim\Documents\RISC-V

While inside the RISC-V folder, I cloned the repository like so:
 git clone https://github.com/wuxx/nanoCH32V003.git

Inside the "doc" folder is the zipfile, CH32V003EVT.ZIP, with "EVT" folder inside.
Unzip the EVT folder into "doc", so you have the example code available.

MounRiver Studio IDE

Download the latest version of MounRiver Studio IDE from the official website:
http://www.mounriver.com/  and install it.

More info concerning the board

 According to the schematic, the LED is connected to PD6

Notes & References
